TYPE-WRITING MACHINE;

SPECIFICATION forming part .of Letters Patent N 0. 734,044, dated July21, 1903 Application filed July 15 1902. Serial No. 115,657. (No model.)

To all whom it may concern:

Be it known that I, JOHN LOUIS CANTELO, a subject of the KingofGreatBritain, residing in Liverpool, in the county of Lancaster,England, have invented certain new and useful Improvements inType-VVriting Machines, of which the following is a specification.

The improvements which are embodied in the devices herein described havereference chiefly to keyboard-machines of the class wherein motion isgiven to the .whole body of type characters when anyone of them isbrought to the printing position, my invention having as its object theproduction of a useful and compact type-writer of pleasing form,ofiering a clear view of the writing in progress and having fewer partsthan are usually required in machines of equal capability.

The type characters are borne by a tubular sleeve and are arranged inthree fields, each .consisting of three columns of type, a shift fromone field to another being made by turning the sleeve. The type-sleeveis thrust endwise by a driving-arm, is caused to rotate by acolumn-selecting device, and is swung bodily downward by impressingmechanism, all these movements cooperating in such manner that anycharacter of the field in use may be selected, brought into position,and printed by depressing a related key-lever.

In the accompanying drawings, which set forth the details of myinvention, Figure 1 is a plan view of the machine. Fig. 2 is a plan ofkey-levers and related parts with spacing mechanism superposed incorrect relative position. Fig. 3 is an end view of the completemachine. Fig. 4 is a vertical section showing the spacing-lever andparts beyond on the rightrhand side of it, the car- 'riage being pushedback and its end'r'emoved.

vation of a portion of paper carriage and platen. Fig. 10 shows detailsprincipally relating to mechanism for insuring certainty in theselection of type characters. Fig. 11 shows details oftype-column-selecting mechanism. Fig. 12 shows under side offieldshifting finger-button. Figs. 13 and 14 relate to mechanism forregulating the width of paper margins. Figs. 15 and 16 are side and rearviews illustrating the action of the inking mechanism.

In. the drawings, A represents a casting, which forms the main frame ofmy machine and is supported-in a usual manner by feet a a. A rod (1Figs. 2 and 4, serves as fulcrum for type-controlling levers B B and BB, a universal impression-bail G, and spacemaking lever X. Sidewisedisplacement of the levers is prevented by passing them through kerfs aa cut in the frame-casting, and springs b b raise them against asomewhat elastic backstop b -made, for instance, of rubber, leather, orthe like. Side pieces 0' c and a middle piece 0, all rigidly connectedby atransverse' rod 0 make up the universal bail, which is kept inposition laterally by extending itsside pieces into kerfs c c, Fig. 2.

The type-sleeve K, Figs. 3 and 4, is capable of rotary and endwisemovement upon a tubular arm I, which projects backwardly overapaper-carriage P from a trunnioned base H, pivoted by screws 71. h, Fig.5, between main lugs a a, belonging to frame-casting A. A longitudinalgroove 10' is formed within typesleeve K to receive a tongue 1' fixed atthe backward end of a rod i passing through the tubular arm I, as shownin Fig. 4. Upon the forward end of rod 1' is fixed a pinion i, havinghelical teeth, which gears with a segment L, correspondingly toothed.The segment L is attached to the forward end of a rod Z, capable ofrotary and lengthwise movement within a tubular arm J, carried by thetrunnioned base H below and parallel with impression-arm I. Animpression-link G connects the lower tubular arm J with middle piece 0of the universal bail.

A rocking frame D, Fig. 4, is pivoted in the bail O by means of acentral rod d, of which the middle part lies Within a notch c in middlepiece 0 and the ends enter holes in side slightly apart to admit of theframe being as shown in Fig. 11.

mounted in the bail. The rocking frame consists, preferably, of a singlepiece of suitablyshaped sheet metal bent into form and strengthened bybeing brazed or otherwise rigidly fixed upon the central rod (1. Fromthe rocking frame D and formed integral therewith rises a driving-arm E,Figs. 1 and 10, having at its upper end a wing e, carried by a loosestud e, which is secured in place by a nut, as shown. The wing e entersan annular groove k formed in a collar k, fixed at the base of thetype-sleeve K, Figs. 3 and 4. Under impulse of springs c 0 coiled onfulcrum-rod (1 Fig. 2, universal bail O rises toward the lower edges ofthe key-levers until antifriction-rollers (1 d Figs. 5 and 7, pivoted inthe casting A on pins d 01 rest within notches d (i which are formed, asshown in Fig. 7, in ends (1 d of rocking frame D. When rollers d d andnotches d d are interlocked, the rocking frame D, a stop-bail F, v

Fig. 5, pivotally mounted thereon, and driving-arm E, which is integralwith frame D, are held in a middle position. The rocking frame is givensuch form, which is preferably that shown in Fig. 2, that some of thetypelevers when depressed engage it backward of its axis of oscillationdin the universal bail O and the rest of them make contact with it onthe forward side ofits axis. The two sets of levers are respectivelymarked B and B in the drawings. A lever of series B when brought downstrikes upon the backward edge of the rocking frame, causing driving-armE to recede from the operator; but a lever belonging to set B, acting onthe other edge of the frame, gives an advancing movement to the arm.Owing to the engagement of wing 9, Figs. 5 and 10, with groove Fig. 3,the type-sleeve recedes and advances upon impression-arm I in unisonwith movements of driving-arm E, Figs. 3 and 4.

On the upper edges of type-levers BB, Fig. 7, are formed projections bb, which are intended to act as stops limiting the movement of stop-bailF. Depression of any type-controlling key-lever carries the projectionbelonging thereto downward into the path of stop-bail F, which is thusarrested, stopping in turn the rocking movement of frame D, on which itis mounted, and sleeve-propelling movement of driving-arm E.

From a depending arm P, Fig. 4, of the helical toothed segment L a pin Lpasses backward through a notch at the upper end of a projection m,rigidly fastened to a comb 'M, Figs. 4 and 5. Figs. 2, 4, 5, and 11 setforth the preferred form of this comb, which extends teeth upward belowthe key-levers from side to side and is supported by sidewisedeflectable hangers m m, pivoted on screws m m in the main frame A, itsendwise movement being limited by pins m 'rn in the hangers m m, whichenter notches in the comb, A type-lever B or B while descendingtraverses the edge of a tooth belonging to hanging comb M and in sodoing swings the comb endwise into a position corresponding with one ofseveral columns of characters making up a type-field on sleeve K. Threesuch columns will be found a convenient number. Such endwise movement ofthe comb M is transmitted through the notched projection m, pin Z, anddepending arm I to segment L, which last, acting on pinion t, turns rodi and thus by means of tongue i rotates sleeve K to bring the column ofcharacters containing the selected type into line with theprinting-point. The typesleeve K maybe provided with several fields oftypeforinstance, th'reeanyone of which can be brought into operatingposition by means of shift-keys-such, for example, as will behereinafter described. Each field should consist of the same number ofcolumns of type, so that any one field can be brought under thecolumn-selecting action of the comb M. During its downward stroke anactuated type-lever B or B depresses the rocking frame, and as notches(Z d are disengaged from rollers (1 (P, Fig. 7, the frame D rocks in theuniversal bail C under the upward tension given to the latter by springsc 0 Fig. 2, causing the driving-arm E, which isintegral with the frameD, to advance or recede until such movement is arrested by contactbetween stop-bail F (which has a limited pivotal movement on said frame)and the intercepting projection 12, belonging to the lever. In itsmovement the driving-arm E by means of the wing c, Fig. 10, engaged withthe annular groove 70*, Figs. 3 and 4, forces typesleeve K alongimpression-arm 1 until the row of type containingthe selected characteris brought opposite the printing-line. In its descent rocking frame Ddepresses the universal bail O and by means of impression-link G, Fig.4, pivoted at its lower end on a pin g and at its upper end on a screwg, which last serves to clamp a clasp or split collar g upon arm J, Fig.5, vibrates trunnioned base H, causing the impression-arm I to bringtypesleeve K down toward the printing position. As this movementproceeds the key-lever by acting on hanging comb M causes that column oftype which contains the selected character to be rotated into thelowermost position. After being broughtopposite the printing-point bycombining the row-selecting action of stop-bail F and intercepting-stopwith the column-selecting action of comb M and key-lever in the mannerdescribed the type character is impressed by a further downward movementof the key-lever, which depresses rocking frame D and universal bail 0without altering their positions relative to each other. The contactedges of the rocking frame are preferably notched away, somewhat asshown in Fig. 5, so that some of the type-levers may have a certainamount of free play before striking thereupon. The two tion in theuniversal bail.

an approximately equal finger depression is obtained throughout thekeyboard.

On collar is are formed as many ratchetteeth 10 Fig. 5, as there arecolumns of type characters on sleeve K and also a flange k Upon thetubular arm J is pivoted by lugs j 3" an oscillating rack j, having asmany notches, preferably of the form shown in Figs. 1, 3, 4, and 5, asthere are rows of type characters. prevented by placing its lugj betweentrunnion H and the clasp or split collar g, which is clamped upon arm J.A pin j is fixed in lug j of said rack, as shown in Figs. 3, 4, and 5. Aspring j, coiled on arm J, turns the rack outward until it is brought torest against pin 7 Fig. 3, fixed in trunnion H. An antifriction-rollerjis pivoted atj in an arm 9 forming part of impression link G. Whenimpression-armI swings downward to the printing position, relativemovement of the parts is such that rollerj is brought into contact withpin j and rackj is thrown over until one of its notches engages flange kwhile its inner angle beyond the notch passes between two of theratchet-teeth 10 as shown in Fig. 5, such interlocking of rack andratchet securing accurate adjustment of typesleeve K with reference tothe printing-point at the moment of impression. While throwing the rack,rollerj traverses on pit] j and finally, nearing its tip, runs upon asloped part, where it ceases to affect the rack appreciably. The lengthof pin j is such that cessation of throw occurs j ust as rack andratchetcollar'become fully interlocked and as a selected type characternears the printingpoint.

The ends fot the stop-bail F, Fig. 7, are notched at f, so as to receiveloosely the axial rod d, and somewhat above this rod said ends arepivoted at f on pins fixed in the ends d of rocking frame D, suchconnection permitting a limited back-and-fo'rward movement of bail Frelative to frame D. A lever 2, Fig. 10, notched at its upper end toengage bail F, is pivoted by a screw 2 to driving-arm E and extendsbelow the axial rod (1, partially inclosing this rod loosely at e andhaving a slot z intended to receive a point 2 belonging to a hookeddetent Z, which hangs from a pin .2 in a lug e fastened to frame-castingA by ascrew 5 A spring 2 is coiled on screw .2 and, as

shown in Fig. 10, its arms press in opposite directions against axialrod cl and a pin Z6, fixed in lever z, tending to keep these twocoincident. Normally the slotted lever z and bail F are retained in amiddle position by the spring 3 and detent-point e is held opposite aprojection d on the rocking frame D,

so that frame D and universal bail 0 cannot be sufficiently depressed toallow of an impression being made until the stop-bail strikes thatintercepting projection which pertains to the actuated key-lever. Whensuch contact occurs, the bail is vibrated slightly relative to therocking frame, and slotted leverz Endwise displacement of rack j is' toprevent the accidental impression of any character other than thatcorresponding with an actuated type key-lever. By springing thedriving-arm E slightly aside after preferably pushing it backward as faras it will go the type-sleeve may be released from wing e and withdrawnfrom the impression-arm.

Type characters are inked on their way to the printing-point afterselection by a roller g mounted on a pin at the end of a nearlyhorizontal inking-arm, which forms part of an elbow-lever Y, as shown inFigs. 3, 4, 6, 15, and 16. This lever is pivoted bya screw g fixedtherein to a vertical pintle y, Figs. 6, 15, and 16, which turns in ahollow post y, rising from the main frame A. The pintley is supported bya head formed at its upper end and resting on the top of the hollow posty. A hole through the pintle-head forms a long bearing. for the body ofscrew y". By thus connecting these parts elbow-lever Y is renderedcapable of two movements onein a vertical planeon its pivot 11 and onehorizontally around the axis of the pintle y whenever this last rotates.A staple g is rigidly fixed in the post 3 and a torsion-spring 11 iscoiled on said post. The spring 11 acts on elbow-lever Y at y. Its pullat this point which would tend to depress the lever Y if the pivot gwere immovable actually elevates the said lever owing to the pivot ytraveling in a horizontal plane on its pintle y under the pull of thespring 3 and taking the lever Y bodily with it, so that the dependingarm Y is held against and tripped upwardly by the immovable staple 'ythus turning the lever Y upward, in which normal position the inking-armY lies obliquely upward toward the left-hand side, as shown in fulllines in Figs. 1 and 4 and in dotted lines in Figs. 15 and 16, and theinking-roller g thus rests in the path of a selected type character. Inaction when the type-sleeve in descending toward the printing positionstrikes upon inkingroller g the inkingarm Y is depressed, but is notcarried directly downward, owing to the abutment of its member Y againstthe immovable staple y The point of contact against the staple yconstitutes a fulcrum on which elbow-lever Y-turns, thus exerting a pullon the pivot y" against the resistance of spring g under the pressure ofthe type-sleeve upon the inking-roller @fi. Owing to the aforesaidmanner in which the elbow-lever Y is pivoted to the revoluble pintle y,the latter is necessarily rotated by this pull on the pivot 3 and theinking-arm Y is constrained to swing toward the right-hand side as thepintle rotates.

Theresultant mo- KOO tion of the combined movements of depression andlateral swing imparts an oblique downward movement of the inking-arm Y,which now takes a position indicated by the full lines in Figs. 15 and16, and thus carries inking-roller across the face of a selectedcharacter and subsequently completely clear of same to one side of thetype-sleeve. When the key is released and the type-sleeve returns, thearm Y is returned by the spring 3 to normal position, as shown in dottedlines. The rear edge of the member Y, which reacts upon staple 3 iscurved slightly outward throughout its length, as shown in Figs. 4 and15, so that the point of contact or fulcrum may roll down away frompivot y as the inking-arm Y is pressed down, thus increasing, in efiect,the length of dependent member Y, and consequently accelerating theswing of inking-roller g aside from the type-path. The hook y Figs. 4,l5, and 16, serves as a back stop, its point catching against staple 3when spring y returns the parts to their normal positions. Inkingroller3 is retained on pin and kept out of contact with the writing-paper by alatch 1 secured to the inking-arm by a rivet y, on which it mayturnstiflly. By raising the forward end of latch 11 its backward part may bedepressed sufficiently to allow of roller 3 being withdrawn from pin 3/.

In order to shift from one type-field to another of, for example, threetype-fields, the toothed segment L, with its supporting-rod l, is movedendwise by a forked arm n, Figs. 2 and 4, which rises from a shift-rod11., extending transversely above the key-levers between pivot-screws nfixed in frame-casting A. Pins 12?, Fig. 11, in forked arm n enter aslot in depending arm P, Fig. 4, of segment L and form a connectionbetween these parts. From each end of the shift-rod n a shift-lever N,Fig. 2, projects forward at the side of the keyboard and carries on ascrew or rivet o ahanging latch O, which bears a double finger-piece 0'atits upper end. (See Figs. 1, 3, and 12.) Either latch may be pusheddown by means of its finger-piece o untilthe upper side of a notch 0Fig. 4, in its forward edge or another,o ,in its backward edge strikesupon a stop-pin 0, fixed in the adjacent side of main frame A, Figs. 1,2, and 4. Each latch is retained in its usual position, which is thatshown in the drawings, by gravity. This position with respect to theshift-lever N is not altered by pressure on a double finger-key 0 beyondits latch-pivot 0 and consequently as the lever N descends the backwardnotch 0 is brought down until its upper side isintercepted bypin 0.Finger-pressure applied forward of screw 0 rocks the key 0 thereon andswings latch 0 far enough edgewise across stop-pin 0 to allow of thisbeing reached by the forward notch 0 The notches are so placed that inbringing one of them opposite stop-pin 0 sufficient movement istransmitted to toothed segment L through lever N, rod n, and arm n (thelast three being rigidly connected) to change the ordinary type-field toone of capital letters; but a field consisting of figures, &c., isbrought under control of the keyboard,while the other notch faces astop-pin. The axial movement of the segment L produces, by means of thehelical teeth, a corresponding partial rotation of the pinion i, andtherewith of the type-sleeve K, to bring about the said change oftype-field. When two shift-keys 0,rigidly connected,and consequentlymovinginnnison, are provided, as shown in the accompanying drawings, inorder to avoid any occasional mutual interference it is desirable thateach latch O gravitate normally into such position that the notch 0therein, which requires the greater depression of lever N to place itopposite the corresponding stop-pin 0, should be capable of reachingthat pin without further adjustment. Apin 0 fixed in shift-lever N,enters a perforation in latch O and allows it only sufficient edgewisemovement to fully cross stop-pin 0, the free end 0 Figs. 2 and 4, of

this latter pin 0 being flattened that necessary swing of the latch maybe as small as possible. Then either shift-lever has been depressed farenough to change the type-field, it may be fastened down by passing theretaining-finger across and beyond the middle line of its finger-pieceo. This movement will rock the finger-piece 0 and swing the latch O onits pivot. untilstop-pin 0 is clutched by the contiguous notch. Backwardextensions of shift-levers N N pass through the outermost of the kerfs aand are bent aside at N N, Fig. 2, to form back-stops,- when the partsreturn under impulse of springs n n to their normal position.

A platen 10, Fig. 1, is pivoted in end brackets P P, belonging to thecarriage 1, which reciprocates in ways or guides in a usual manner. I

A paper-guide S, Fig. 9, made of sheet metal and having a longitudinalfold 3 formed therein, is fastened at 8 Fig. 4, along its lower edge tothe carriage-slide. Tensionrollers s s s are fixed on a rod 5 whichforms a common pivot for them and lies in the fold s portions of thefold and of adjacent parts of the guide being cut away where necessary,as shown in Fig. 9. Guide S is so adjusted and fixed to thecarriage-slide that it presses rollers s s s with about equal force uponwriting-paper passing between them and the platen p.

On the uppermost edge of paper-guide S is engraved or otherwise formed ascale 5, consisting of broad marks and spaces, as shown in Figs. 1 and9. Increased legibility is secured by the use of such scale divisions,as characters when impressed along the printing-line appear alternatelyopposite broad marks and spaces, both as wide as the charactersthemselves, instead of successively before narrow lines, such as areordinarily employed to indicate scale divisions.

A grooved rod E, Fig. 1, is supported by the carriage ends PP and bearssliding tubes '1" r, having. dependent stop-fingers r r, Fig. 9. Thesestop-fingers fall into engagement with an escapement rack 9, fastened byscrews 19 p to carriage P, the stop-finger tips being formed to fit thespaces between adjacent rack-teeth. Internally each sliding tube r islarge enough for the greater portion of its length to receive a springof the form shown in Fig. 14, which spring incloses the rod R and iskept in place by a collar r, Fig. 13, driven into the tube. End 1" ofthe spring projects outward through a slot in tuber, and the other end ris turned back lengthwise within the body of the spring, as shown, so

' as to lie and be capable of moving smoothly in groove R when tube 7"is pushed along rod R.- The carriage P isirnpelled toward the left handby a spring-drum T, acting through a cord t, Figs. 1 and 3.

On screws u, Figs. 1 and 2, fixed in lugs forming part of the main frameA, is pivoted a spacing-finger U, having a lateral projection u, whichintercepts the advancing righthand stop-finger 1" when a line of writingis complete, bringing the carriage to rest. Similarly when the thecarriage is returned in order to begin a line of writing the lefthandstop-finger is brought against the spacing-finger edge at u", Fig. 2,where an oblique facet parallel with the backs of the rack-teeth isformed. By giving stop-facet a the angle shown impact'between it and thearrested stop-finger cannot cause displacement of the latter from thetooth-space in which it rests. Consequently a rack having teeth of theordinary shape, with square faces and inclined backs, can be used. Thesliding tubes 1' r, Fig. 9, may be adjusted upon rod R in such mannerthat their fingers r r will arrest carriage movement, so as to secure aprinting-line of any desired length anywhere within the limits shown byscale 8. Points r r Fig. 1, projecting from the movable tubes, indicateupon scale s the position of initial and final characters. Consequentlythe length of a line of writing and the width of margin left at bothedges of the paper are also apparent.

Fixed to grooved rod R is a bail-like clip g Fig. 1, which is intendedto keep the paper down upon the platen along the printing-line. Tensionis put upon paper-clip g by the springs T 7' Figs. 13 and 14, which alsohold stop-fingers r r in engagement with the escapement-rack 19', Fig.9. Endwise movement. of rod R is prevented by a screw W, the tip ofwhich enters an annular groove near the end of the rod.

On a post t Figs. land 2, fixed obliquely in the main frame A, ispivoted a bell-lever t, which is preferably madc'of wire, its middlepart being formed into a coil to fit the fulcrum-post 25 as shown. Oneend of the Wire lever is weighted and carried within a bell T to act asclapper-thereto. Its other end isbent, as shown in the drawings, ananlever rebounds until its free end beyond heel i rests against the faceof stop -finger 'r, whereit remains until the carriage is returned tobegin a fresh line, when owing to the obliquity of its fulcrum-post 25the clapper falls fully back into its usual position. I

A spacing-link W, Fig 4, is pivoted to the middle part of a lever 10,which is placed intermediately between the space-making lever X and themiddle piece 0 of the universal bail 0, one end of the intermediatelever w being connected by a link to, pivoted on a screw m, with thespacing-lever X, so as to be depressible thereby, while its other end isattached by a pin 10 to the middle piece 0 of the universal bail O anddescends therewith when any type-controllinglever B B is pushed I down.When owing to movement of either universal bailor spacing-lever onlyoneend of, the intermediate lever 10 is depressed, turning upon the pivotat its other end, it draws the spacing-link WV down ward through adistance less in proportion as ils point of attachment on thelever nearsthe fulcrate end thereof. Coincident descent of a type-lever B or B andspacing-lever X depresses the intermediate lever to bodily and drawsspacing-link W downward through a distance equalingin amount the sum ofthose movements resulting from two separate strokes made by the samelevers. At its upper end the spacinglink W is connected by a screw 40with spacing-finger U, Figs. 2 and 4, to the under side of which on ascrew 1; is pivoted a spacingpawl V. A stepped stop 10 10 projectsbackward from the upper end of spacing-link W, opposite a lateralextension 41 of the spacingpawl. A spring 11 secured at o to thespacing-finger, presses against a flat formed at the base of pawl V andimpels it toward a position in which its tip is somewhat more than thewidth of two teeth of rack 19' to the right ofthespacing-fingertipu.Usuallythespacing-finger U is supported by spacing-link W in a positionwhich brings the spacing-pawl tip between two rack-teeth, and thecarriagespring overcoming the resistance of spring 0 then turns the pawlleftward until its tip I will be that next succeeding if a single leveris actuated, but the second following one if a type-lever andspacing-lever X are pressed at the same time, the pawl movementdepending on the depth to which spacing-link W carries its steppedprojection 10 w Any lever B or B, acting through the universal bail O,or the spacing-lever X, acting through the short link to, can depressbut one end of the intermediate lever to and communicates, therefore,only sufiicient movement to link W to place step 10 in the path of pawlextension v; but when a lever B or B and the lever X act together theintermediate lever 20 being depressed bodily brings the spacing-link Wdown far enough to carry step 10 past pawl extension '0 which is thenintercepted by step 105 when the spacing-pawl tip has moved over adouble space. Thus the space following a word may be made at the sametime that its last letter is impressed. Upon return of the various partsto their usual positions pawl V is replaced leftward by rack p as thecarriage makes a spacing movement. The stepped projection w 10 is cutaway at w, Fig. 1, in order that it may return from its lowermostposition without catching beneath the pawl extension v When the carriageis pushed backward toward the right-hand side of the machine, therack-teeth tilt spacing-pawl V until they can pass its tip. It thespace-lever X is pressed at this time, the pawl-tip will be brought downupon a fixed pin 1;, Fig. 4, in the framecasting and held in its tiltedposition, leaving the carriage free for movement in either directionuntil the space key is released. Space-key lever X is preferably formedof a single piece of sheet metal. Its downward movement is limited by astop 00'.

The printing-point is located by an indicator n Figs. 2 and 4, made ofthin flexible metal and secured to the spacing-finger by a screw {04. Asthe type-sleeve descends to make an impression, indicatoru is withdrawnfrom its path and below the printing-line by the spacing-finger.

A line-space lever Q is pivoted on a gudgeon 19 Fig. 8, fixed in theplaten end, lateral stiifness being secured by a tubular boss Q, whichis a part of the lever. On the gudgeon p is formed an annular rabbet toreceive a ratchet-wheel p, which is clamped securely, so as to turn withthe platen, by a screw 1). The head of this screw forms the platen-pivotturning in the end bracket of carriage P. A hooked pawl q, Fig. 4, ismounted on a screw 1 Fig. 8, fixed in linespace lever Q. This lever alsocarries on a pin (1 Fig. 9, an antifriction-roller 1 which is placedbelow an end of the paper-clip g Figs. 1 and 9, in order that this clipmay be raised off the writing-paper when platen p is rotated to make aline-space. A pin q, Fig. 9, fixed in carriage-slide P, forms aback-stop for lever Q when it is returned to its normal resting positionby the pressure of paper-clip g on roller (1 The line-spacing movementis regulated by a thin lever q, of sheet metal, mounted loosely onplaten-pivot 19 Fig. 3, and having a ledge (1 Fig. 4, at its lower end,which may be brought by a finger-piece q at its upper end into the pathof a shoulder on space-lever q. The line-space regulator is secured bydropping its finger-piece q into a notch formed in the adjacent carriageend, there being as many such notches g Figs. 1 and 3, as there arewidths of linespace provided for in the machine.

A slot a Fig. 1, allows the driving-arm to rise through the mainframe-casting, in which other suitable openings are also made for thepassage of impression-link G, spacing-link W, and notched projection m.

I declare that what I claim is- 1. In a type-writing machine, thecombination with a type-sleeve mounted on an arm adapted to beoscillated by finger-key mechanism to make an impression of a typecharacter, and means for shifting said sleeve axially on the arm tobring a selected row of type into printing position; of a rod revolublymounted within said arm, means forlocking said rod at its backward endto the typesleeve as regards relative rotation, while permittingindependent axial movement of the sleeve, and means for more or lessrotating said rod and therewith the sleeve under the action of thefinger-key mechanism to bring a selected column of type into lowermostposition, substantially as described.

2.
